Arithmetic expressions can be formed with the operators +, -, *, /, MOD, and DIV. The four last operators are stronger binding than the first two. Any processing sequence can be enforced by parentheses.
An arithmetic expression usually provides a numeric value. It results in the NULL value, however, if
- one of its operands results in the NULL value.
- division by 0 is attempted.
- the valid range of values is exceeded.
- a literal or a variable value cannot be interpreted as a number.
